Debbie, not sure of your exact requirement but we have done this recently.
Requirement was to provide real time data from both IBMi DB2 and MSSQL to
a PHP Zend server running on IBMi.
The data returned to the PHP request was all JSON.
We used a Monitor program that receives request on a data queue and
retrieves the required data from the multiple data bases and returns the
data in JSON.
We used SK's YAJL to format the JSON See
If you would like additional details let me know.
